Well Hi-Fidelity isn’t for everyone, regarding Trinnov they were initially developed so that a mastering engineer could transplant his acoustic into an unfamiliar studio.
They are powerful, my concern with all of the room correction software I have tried is that they are correcting regions of the FR which really shouldn’t be corrected ie non-minimal phase. I feel It preferable to get a decent pair of speakers and then just adjust the very gross errors with just a touch of EQ.

We were the first Uk Trinnov importers, back then the units corrected to a flat ( horizontal ) target curve which no domestic user enjoyed, I understand GLM,Dirac,Trinnov etc for studio use but am not convinced for domestic reproduction, where I feel ( with a good pair of speakers) less is more.

ATCs are extremely traditional, with no adjustability whatsoever, and their measurements are really no better than the B&Ws , there are speakers available which are designed to ameliorate the effects of the room.
But firing across the room looks to have improved things considerably.

If you push the speakers right back against the wall you will increase bass reinforcement , which you can ameliorate with EQ, on the positive side you will be removing the speakers own rear cancellation.
Every ‘pro’ manufacturer recommends placing the speaker between 10-60cm from the front wall to void cancellation.

If the OP uses a touch of EQ to reduce that 45Hz peak, ( create a filter, -re-measure , listen repeat) then unless he is prepared to install massive bass trapping or subwoofers in a sink/source arrangement that is the probably the best sound quality he can achieve in that room, the B&W’s aren’t bad speakers.
